'ro ALL WHOM rr MAY CONCERN:

Be it known that I, EMMET R. AUSTIN, ofthetown of Norwalk, county o? Fairfield, and State of Connectient, have invented a new and useful Improvement in the Mode of Constructing Core-Flasks, to be used in casting the iron buckets for water-elevators; and I do hereby declare that the following is a correct description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement of an adjustable supporting steady-pin.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same. The drawing- A l Figure 1, is a face view of the ask in two halves, with the steady-pin attached.

Figure 2, a view of a core after being formed for use. y

The ask, A, is made in two parts, hung with hinges, to fold together in the usual manner, with proper steady-pins, G, and fastenings, H and I. Each half of the flask has the necessary indentatons, Il, and sunk recesses, K, to receive the end of the wire C, and the other peculiar formations required to give theproper shape to the core, iig. 2. The wire C is formedv with an eye at each end, K K. One eye makes the bail or liftingpart of the bucket., and the other end passes through the bottom of the bucket, and the two are connected together by a short chain, that is, the lower one and upper one of each bucket, when in operation, to allow the same to pass over the grooved periphery of the elevator-wheel.

In forming the core, one eye of the wire C is placed in the sunk recess on the face ofthe flask A; the other end will be supported centrally by the adjustable horizontal steady-pins D D, as shown in the drawing, fig. l. At the upper end of the flask A, I attach permanently the two pipes E E, of a proper size to receive the adjustable sliding steady-pins D D. These pins pass through the pipes E E, and the inner end of each is forked, to clasp the wire C, to hold and support the same centrally while ramming the material to form the core F, iig. 2; and when the core is formed, the iiask will be opened, the'two movable pins D D withdrawn, allowing the completed core to be taken out. I

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the hinged desk A and A with the pipes E -E and adjustable steady-pins D D, all constructed and arranged substantially as described.
